I am going to post this to clarify my earler message. I am not a relative. I believe you are correct. I doublechecked on the burial locations to verify this. Abraham Marion and Mary Marion are buried in the Tennessee Cemetery, an old cemetery where many of the relatives from Tennessee are buried. Rhoda was buried at the Columbus City Cemetery. Apparently, Abraham II did not have a headstone as there is no record of two Abrahams in the cemetery records that I can locate.
As you may know, the LCGS checked WPA records against the printed cemetery book when putting up the on line database. we are still trying to track errors.
Do you know if Abraham Marion, II was buried here or if he left the county after his wife's death? Only a small handful of Marions were buried here or their monuments are gone.
